Steganographic encoding and detecting for video signals
First Claim
Patent Images
1. A method comprising:
- obtaining a plural-bit identifier;
obtaining a signal representing video data; and
cyclically applying, using a processor, the plural-bit identifier to the signal representing video data using one or more pre-computed carrier signals, wherein the plural-bit identifier is steganographically applied to the signal representing video data, wherein a separate, pre-computed carrier signal is utilized for each bit of the plural-bit identifier when applying the plural-bit identifier to the signal representing video data.

Abstract
Aspects of the invention relate generally to steganography, data hiding and/or digital watermarking for video and other media signals. One claim recites a method including: obtaining a media signal comprising a message steganographically embedded therein; obtaining information obtained from the media signal; adjusting a message detection process with reference to the information; and detecting the message from the media signal according to the adjusted message detection process. Of course, other combinations are provided as well.

7. An apparatus comprising,
one or more electronic processors configured to: -
obtain a plural-bit identifier; obtain a signal representing video data; and cyclically apply, using one or more pre-computed carrier signals, the plural-bit identifier to the signal representing video data at the time of or as part of distribution of the video data, wherein the plural-bit identifier is steganographically applied to the signal representing video data, wherein a separate, pre-computed carrier signal is utilized for each bit of the plural-bit identifier when applying the plural-bit identifier to the signal representing video data. - View Dependent Claims (8, 9, 10, 11)
